NICU is neonatal intensive care unit. It is also called as an intensive care nursery. The main role of an NICU in the hospital is care and treatment of newborn infants who are premature (premie) or develop some medical problems immediately after birth. A complicated pregnancy, ecclampsia, early onset of labor and sudden accident during pregnancy are all conditions that are responsible for babies being born before their actual due date. Every week of pregnancy entails changes and new developments in the baby and nature has so designed the 9 months that at the end of this period the baby is fully formed and mature. At this stage it is ready to be born and so if the birth occurs before this time period, then the early birth baby needs to be kept in an environment similar to the mother’s womb so that it can grow and survive. The preterm birth complications are effectively dealt with in the NICU.

Baby Care Tips in NICU

The sights and sounds of the NICU and small babies on life support can be very overwhelming for a new mother but you need to be calm and trust that it is the best thing for your baby.

Mothers are allowed to visit the NICU wearing sterile clothes and footwear so that the infections from the outside do not affect the baby. Feeding the baby in the NICU is allowed if the baby is able to breast feed. If the baby is very unwell, then expressed breast milk is fed to the babies by the nurse with the help of a feeding bottle or nipple.

Care of preterm baby is very difficult as a lot of care needs to be taken to avoid infection. They are too small and very susceptible to the slightest exposure. NICU babies are at a risk of developing infections related to the catheter or tube that is inserted to feed them. Complete sterilization and asepsis needs to be maintained in the environment of the icu.
